Double-injection gas valve

Abstract

The invention relates a double-injection gas valve which comprises a valve body provided with an air inlet channel and a main air outlet channel. A valve core which can rotate is arranged in the valve body; a ventilation chamber of which an opening is downward is formed in the lower part of the valve core; a first strong fire hole and a slow fire hole which are communicated with the air inlet channel and the main air outlet channel are formed in the side wall of the ventilation chamber of the valve core; and a main nozzle is mounted at the air outlet end of the main air outlet channel. The double-injection gas valve is characterized in that a secondary air outlet channel is also arranged in the valve body; a secondary nozzle is mounted at the air outlet end of the secondary air outlet channel; a second strong fire hole which is communicated with the air inlet channel and the main air outlet channel and a supplementary fire hole which is communicated with the ventilation chamber and the secondary air outlet channel are also formed in the side wall of a ventilation chamber of the valve core. The gas valve only passes through a rotary valve rod to reach a certain position, so that two nozzles are maintained in a state of simultaneously injecting gas, hands are not needed to keep in a pressing operation position, and the operation is more personalized.

Description

technical field [0001] The invention relates to a gas valve used in a gas cooker, in particular to a double-jet gas valve capable of outputting a fire with a high calorific value. Background technique [0002] The cock valve in the gas cooker is a manually operated valve that controls the gas source supply. Ordinary plug valves generally include a valve body with an air inlet channel and an air outlet channel. The valve body is equipped with a rotatable valve core. The valve stem that the valve core rotates, the lower end of the valve stem holds the spring that keeps the valve stem moving up and out of the connection with the valve core. To communicate with the large fire hole and the small fire hole of the air inlet passage and the air outlet passage. When in use, the user operates the valve stem through the knob on the operation panel. Generally, the knob is first pressed and turned counterclockwise to drive the valve core to rotate counterclockwise, so that the large fi...

Problems solved by technology

In today's energy shortage era, in many countries, it often happens that the gas source of the entire residential area needs to be changed. Because the gas source is different, the gas flow required by the gas appliance will be different, so the original installation is only for one type. The ordinary gas valves and corresponding nozzles of the gas need to be replaced, which greatly increases the replacement cost, which is not conducive to the promotion and application of new gas sources, and is also not conducive to the implementation of gas source replacement work.
